To help with this, the Sensics team decided to create a simple iPhone app (Android version coming soon) that helps with these calculations. This app is now available as a free download from iTunes. Think about it as public service for the VR community.
In it's current beta form, the app provides several useful conversions:
- TV screen size to/from goggle field of view
- Screen size and aspect ratio to/from field of view
- Quaternion to/from Euler angles
The app also includes useful reference info as well as a way to ask the VR experts at Sensics.
Some of this math already appeared on this blog such as here and here, but it is now available in your pocket.
What additional calculators would you find useful? What changes would you like to see in the app? Any bugs that need to be fixed? Let me know.
